摘要：

<正> Minimum fluidization velocity of quartz sand and glass bead under different pressures of 0.5,1.0,1.5 and 2.0MPa were investigated.The minimum fluidization velocity decreases with the increasing of pressure.The influ-ence of pressure to the minimum fluidization velocities is stronger for larger particles than for smaller ones.Based on the test results and Ergun equation,an experience equation of minimum fluidization velocity is pro-posed and the calculation results are comparable to other researchers' results.
